doc/usage/extensions/autosummary.rst

@@ -61,63 +61,63 @@ The :mod:`sphinx.ext.autosummary` extension does this in two parts:
    :event:`autodoc-process-docstring` and :event:`autodoc-process-signature`
    hooks as :mod:`~sphinx.ext.autodoc`.
 
-   **Options**
+   .. rubric:: Options
 
-   * If you want the :rst:dir:`autosummary` table to also serve as a
-     :rst:dir:`toctree` entry, use the ``toctree`` option, for example::
+   .. rst:directive:option:: toctree: optional directory name
+
+      If you want the :rst:dir:`autosummary` table to also serve as a

             :toctree: DIRNAME
 
             sphinx.environment.BuildEnvironment
             sphinx.util.relative_uri
 
-     The ``toctree`` option also signals to the :program:`sphinx-autogen` script
-     that stub pages should be generated for the entries listed in this
-     directive.  The option accepts a directory name as an argument;
-     :program:`sphinx-autogen` will by default place its output in this
-     directory. If no argument is given, output is placed in the same directory
-     as the file that contains the directive.

-   * If you don't want the :rst:dir:`autosummary` to show function signatures in
-     the listing, include the ``nosignatures`` option::
+   .. rst:directive:option:: no-signatures
 
-         .. autosummary::
-            :nosignatures:
+      Do not show function signatures in the summary.
